IDT Corp, the company that makes the Internet Telephony phone client Net2phone, is expanding its service worldwide. The service they are touting is at the moment is a mixture of internet telephony and international call-back service. Something borne of Hackensack, New Jersey-based IDT’s background as a discount call- back service. The organization only has one server site in New Jersey, so callers use the internet to route their call to the site, and then the call is routed across the national or international telecoms network to the desired destination. This near but no cigar internet telephony is being supplanted by a new US service IDT will launch in two weeks, using Unix servers running in various US States. The network wil be offered internationally in October. This involves international third parties buying the servers and being paid part of the fees IDT charges its customers. The service will support PC to phone and phone to phone connections. But IDT isn’t making much money out of its internet telephony business as yet which has been running for a year, in the last quarter it brought in $1.1m in revenues. The client software is free of charge, and a fee is charged for the use. So how their satisfaction or money back offer works is a mystery.
